Partition limits in Ubuntu

Asked by Jackie

I have a new seagate 250 ATA drive. Its still clean. When I tried to install Ubuntu on it it recognizes the drive and the size, but when I try to partition it I seem to be limited to 4 partitions, the last one being unusable, no matter the size. I have been trying to partition it into 40 gig partitions, but the last one at 90 gigs is unusable, if I go back I can leave just 8 meg unusable, but then I have 130 gigs that I cant partition, how do I get past this bump?

by default only 4 'primary' partitions can be created on any hard-drive running any opperating system, you can however create 'extended' partitions that lets you have as many as you wish.

if you are partitioning with 'gparted' (also known as the gnome partition editor) you should get a window such as this when you create a new partition:

you should change the Create as drop down box to 'extended' when creating the partitions

That looks like it, but it stops me from getting what, maybe six partitions? I end up with several reasonably sized, and one huge partition. <i> "by default only 4 'primary' partitions can be created on any hard-drive running any operating system" <i> Not so, with XP I can partition my hard drives as I want.

no its the way hard-drives work. xp just hiding the fact that it is using extended partitions. the way extended partitions work is you create one large primary partition then put smaller extended partitions inside it. back in the old days it was never even dremt of that someone might want more than 4 partitions (or even that a hard-drive could have so much space that more than four would be possible), its just something left over from that.

Okay, so there are only 4 partitions allotted...nonetheless, what steps do I need to take to create additional partitions, and can I name them in Ubuntu?

You can create you base partition, then add a single extended and make more partitions within the extended partition, and yes you can set the names of mount points in ubuntu using gparted.

Can you help with this problem?
